None of the 22 native species of bumblebees in ������ý���� County showed declines over a recent five-year period, according to a new CU ������ý���� study. Two species previously believed to be disappearing were present in several locations. "It shows that ������ý���� County is doing something right," the study authors say.

Arctic sea ice was at a record low maximum extent for the third straight year, according to scientists at the National Snow and Ice Data Center (NSIDC) and NASA.

A new study on Baffin Island in the Canadian Arctic shows that the Barnes Ice Cap, the last remnant of the ice sheet that once blanketed much of North America, will disappear in a few hundred years.

Older vertical oil and gas wells are more likely to cause groundwater contamination than newer wells, new CU ������ý���� research shows.

Humans have dramatically increased the spatial and seasonal extent of wildfires across the U.S. in recent decades and ignited more than 840,000 blazes over a 21-year period, according to new ������ý����-led research.

Thanks to a six-year $6.8 million renewal grant, decades-long data collection will continue on Niwot Ridge. It is the only site of its kind on the continent comprising alpine and sub-alpine environments, and CU ������ý���� researchers sometimes brave harsh weather conditions to get there.

Dust released by an active coal mine in Svalbard, Norway, reduced the spectral reflectance of nearby snow and ice by up to 84 percent, according to new ������ý����-led research.

A study of Front Range forests burned by wildfires between 1996 and 2003 shows they are not regenerating as well as expected and large portions may become grasslands or shrub lands in coming years.

The recent “atmospheric river” weather pattern that pummeled California with storms from late December to late-January may have recouped 37 percent of the state’s five-year snow-water deficit.

Rapid evolution at the edges of a given species habitat may play a larger role in population expansions than previously suspected, according to the results of a new ������ý����-led study.
